Document Summary
People of differing ages all studied at the same time. Babies of different ages are compared on a given behavior over a short period of time. Same infants studied twice or more over a substantial length of time. Useful for revealing stability and change over time. Whether infants who respond most reliably to their own name at 4 months understand more words at 9 months. Same groups of different-aged people studies repeatedly as they change ages. Their ability to recall different word lists every birthday for 5 years. Can reveal links between early and later experiences and development. Age difference may reflect cohort differences, not developmental effects. Can still leave questions about generalizability beyond test cohorts. Same participant(s) studied repeatedly over a shorter period of time as they master a task. Designed to provide in-depth depiction of processes that produce change. Discovering how solving problems is an inherently rewarding experience attrition, practice effects.
